v CARBON BURNER'.

Application filed May 29, 1325. Serial No. 33,766.

This invention relates to a carbon burner or mixer attachment 'forfurnaces, and an object of the invention is to provide a burnerstructure for attachment to 'urnaces or the like, which will mix oxygenor air with the carbon monoxide gas which forms within the fire-box ofthe furnace, and renders the carbon monoxide gas inflammable and causesit to ignite and burn in the furnace, thereby deriving the maximumamount of heat from the 'fuel used. v

Another object of this invention is to provide aburner as specified,which includes 'a frustro-pyramidal body having a wedgeshaped inletopening at its large end and provided with a plurali'ty of battlesarranged staggeredly to cause a sinuous movement to the air or oxygen asit passes through the burner to insure preheating of the oxygen or airprior to its admission into the furnace and also to provide battles,certain of which are inclined from their center towards each edge fordividing the entering air or oxygen to cause it to travel in twodirections through the preheater or burner structure.

Another object of the invention is to provide a burner as specifiedwhich is simple in Construction, requires no adjustments, and one whichmay be easily and quickly as well as nexpensively installed.

Other objects of the invention will appear in the following detaildescription, and in the accompanying drawings wherein:

Figure l is a side elevation of the improved burner.

Figure 2 is a longitudinal section through the burner.

Figure 3 is an end elevation of the i-nlet end of the burner.

Figure t is an end elevation of the outlet end of the burner.

Referring more particularly to the drawings, the improved carbon burnerincludes a substantally frustro-pyramidal body 1 which has three of itssides cast integrally and the last or fourth side 2 attached thereto bymeans of a toe and heel joint 3, and lugs 4. The lugs 4 are formed uponthe edges of the sides 5 against which the side 2 rests. The inlet end 6of the burner structure is provided with a wedge-shaped inlet opening 7at its center, through which opening the air enters the body l. As theair enters the body 1, it engages against the baflle 8 whi-ch inclnestowards the inlet end 6 from each edge of the battle toward its centeras clearly shown in Fg. 2 oi the drawngs, for bisecting the infiowingair anddirecting it in opposite directions transversely through thebody. The air passes about the ends of the baflie 8 and is defiectedinwardly towards the longitudinal axis of the body along the surfaces ofthe baii'les 9, passing through the space between the facing ends of thebattles 9 and against the baflle 10, which again bisects the stream ofair and directs it transversely along the sides and then about the endsof the battle 10. This sinuous and bisecting movement of the air is keptup throughout the entire 'length of the body l` by means of the variousbafiies 8, 9, 10 and 11, and the central short battles 12 which are nearthe outlet end. The baflies 12 incline from their outer edges inwardlytowards the outlet end or in the opposte direction to the inclining ofthe bames 8 and 10. Outlet is had from the body l through the openings13 in the plate 14: and the openings 15 in the outer end 16.

The inlet opening 7 is positioned at the center ot' the inlet end 6 andperpendicular to prevent any cooling efi'ect and admits the air oroxygen nwardly to the defiecting plate8 which bisects the flow as abovespecified, and causes the incoming oxygen or air to enter the variousstages within the body 1 during which time the air is retarded anddeflected so as' to cause thorough dissemination and expansion forabsorbing heat so that as it passes out of the body it is superheatedand the defiector is neutralized with a the defiector within the furnaceso that it will mix thoroughly and efliciently with any carbon mono-xidegas within the furnace, changing the gas to carbon dioxde and causingits instantaneous ignition and the releasing of the heat unitstherefrom.

The inlet end 6 has bolt receiving bosses 17 which are adapted toreceive suitable bolts for attaching the burner to a furnace and if itis so desired, a sheet of asbestos as indicated at 18, may be placedagainst the outer surface of the inlet end 6 and held in place by thebolts used for attaching the burner to a furnace.

Adjustments are not provided for regulating the inlet of air as the flowof the air or oxygen through the burner is automatically regulated bythe regular approved type of draft dampers (not shown) used on llU thefurnace in connection with which the burner is used, and the inletopening 7 is of sufiijient size 'or maximum inlet of air.

From the foregoing description taken in connection with the accompanyngdrawings, it Will be apparent that a burner has been provided which issimple in Construction, durable, may be cheaply manufactured, andinstalled, and one which Will result in the thorough and completeutilization of the heat producing proclivities of the fuel used.

It is, of course, to be understood, that the invention may beconstructed in various other manners and the parts associated indifferent relations, and therefore, I do not desire to he limited in anymanner, except as set forth in the claim hereunto appcnded.

hat I claim is A carbon monoxide burner comprisng a rectangular bodytaperng from its inlet end to the outlet end thereof, said body providedin the face of its inlet end 'with a centrally and vertically disposedslot having inclined side edges tapering towards the upper end with theends of said slot extended adjacent the outer wall of said body, aplurality of relatively small staggered outlet apertures provided in theoutlet end of said body, a. plurality of integrally formed verticalpartitions equally spaced within said body, said partitions laterallyextended from opposite sides of said body and divided centraliy toprovide a passage there between, a plurality of integrally formedbafl'le plates disposed intermediate said"partitions with the endsfhereof terminating adjacent the said opposite sides to provide a secondpassage on each side of said first named passage, said bathe platesinclined from their outer ends to the centers thereof to bisect anincoming stream of air towards the free ends of said battle plates andthrough said first named passage to provide a sinuous path through saidbody substantiaily as described.

In testmony Whereof I affix my signature.
